• Montezuma Micro CP/M Hard Drives

    From Tom Lake@21:1/5 to All on Thu Apr 20 21:50:49 2023
    I have the drivers for a and 15 Mb drives but the instructions say there's also a driver for a 35 Mb drive (HDRS35M.COM) but it's not on the MMRSHD.DSK image I have. Does anyone have the image that includes HDRS35M.COM so I can use a 35 Mb drive?

    Tom,
    In all the files I have for MMCPM231 I did not find the HDRS35.COM. There is a text file with a lot more
    drivers showing. I don't find any of those file either.

    Hey I finally found HDRS35M.COM!! It's at

    https://www.trs-80.com/cgi-bin/down-ok-model4.pl?mmcp22hd.zip

    I still can't get it to work to create four partitions, though. The last partition always errors out on track 512.

    I finally found HDRS35M.com. It's on an image on Ira Goldklang's TRS-80 site. Go to

    https://www.trs-80.com/wordpress/archive-search/

    and search for "hard drive support" (minus the quotes)
    then download Montezuma Micro CP/M v. 2.2 Hard Drive Support [Original]
    That has all the Radio Shack drivers on it. I still can't find the other makers' drivers, though.
